It is important to start the fight against the virus as soon as it is detected, but it usually takes a long time to invent a vaccine, approve it, and distribute it [1]}. It is therefore important to contain the spread of the virus until the time when vaccination becomes available.
The recent COVID-19 pandemic has shown that it is of paramount importance to reduce the number of patients that have to be treated at the same time in intensive care units (ICUs) to avoid the risks that hospitals run out of capacity. To reduce this number, non-pharmaceutical means, such as contact restrictions, will be effective[2]}. The question, which contact restrictions are most effective, is a topic of ongoing research [1]}.
